STEAM COOKING APPARATUS.

Specification of Letters Patent.

Patented Apr. 29, 1913.

Application filed July 2, 1912. Serial No. 707,312.

To all whom it may concern Be it known that I, WILLIAM C. SALMON, acitizen of the United States, residing at Gold Hill, in the county ofJackson and State of Oregon, have invented new and useful Improvementsin Steam Cooking Apparatus, of which the following is a specification.

This invention relates to steam cooking apparatus and has for an objectto provide apparatus of this character in which the water ofcondensation may be commingled to produce a consummated element orliquid which can be served as soup and to provide means whereby theelement may be flavored as it is drawn from the apparatus.

Another object of the invention is to provide an im roved audible alarmwhich will be sounde on the fall of the water below a predeterminedpoint in the steam generating chamber so as to inform the user that thesupply of water must be replenished.

Another object of the invention is to provide a steam cooking apparatuswhich will include companion vessels that are connected with each otherso that they may be readily disassembled whereby they may be subjectedto a suitable cleansing bath and maintained in a highly sanitarycondition.

Another object of the invention is to provide steam cooking apparatuswherein the distributing steam pipe and the drip pipe may be exteriorlylocated upon all of the difierent vessels so that each vessel willpossess a maximum interior area to accommodate a large quantity ofmaterial.

Another object of the'invention is to provide means in the dripreceptacle whereby the commingled elements will be visible exteriorly soas to indicate to the user when the liquid has been properly consummatedand is ready to be drawn oif.

In the drawing forming a portion of this application, and in which likeletters of reference indicate similar part-s in the several views:Figure l is a vertical longitudinal section through the apparatus. Fig.2 is a similar view showing a slightly modifled form of the invention.Fig. 3 is a perspective view of the combined strainer and flavoringextract container. Fig. 4 is a section on an enlarged scale through theboiler and through the combined gage and alarm.

The apparatus comprises a steam generating water chamber or boiler 1which is.

open at the top, provided with an inlet aperture 2 and a combined guardand funnel like member 3 which is disposed at one side of the boiler andwhich opens in the direction of the aperture 2 whereby the supply ofwater may be replenished at the convenience of the operator. Receptacles4, 5, 6 and 7 of practically similar construction are superimposed withrespect to the boiler 1, the lowermost section being fitted theretowhile the similar upper sections are detachably fitted together, eachsection being provided with an external annular bead 8 which restsuponthe upper receptacle and a depending flange 9 which frictionallyengages the inner walls of said adjacent receptacle whereby a steamtight connection is effected at the points between all of the sections.The receptacle 4 is provided with a main bottom 10 and a supplementalbottom 11, the latter having perforations 12 therein and spaced from themain bottom 10 so as to provide an intervening drip chamber 13therebetween. The boiler 1 is provided with an elbow 14, while each ofthe receptacles A, 5, 6 and 7 is provided with a steam conveying pipesection 15, the uppermost section having removably fitted thereto a cap16. These pipe sections are fitted together in substantially telescopicmanner whereby they are disposed in line with each other, and as shown,each section is provided with a branch portion or tube 17 which opensinto the receptacle with which the particular pipe section isassociated. From this construction it is evident that as steam isgenerated in the boiler section 1 of the apparatus it will be conveyedthrough the re spective pipe sections 15 and then to the companionreceptacles 4, 5, 6 and 7 so that the food articles in the diiferentreceptacles will be subjected to the full action of the steam.

The receptacle 4 is provided with a drip duct 18 while each of thesections 5, 6 and 7 is provided with a drip tube 19. These tubes areconnected with each other in substantially telescopic manner and asillustrated the tube 19 of the receptacle 5 has its lower endfrictionallyengaged in the upper end of the drip duct 18, the said upperend of the duct being exteriorly located upon the receptacle 4 while thedrip tubes 19 are correspondingly located so that each cookingreceptacle will possess the maximum interior area. For the same reasonthe steam conveying pipe sections 15-are also exteriorly located uponthe apparatus. The tube 19 of each receptacle is provided with one ormore perforations 20 which open into the receptacle so that the wastesteamwill be conducted to the tube for a purpose to be hereinafterexplained. Each drlp tube carries a valve 21 which may be influenced orcontrolled manually throughthe lever 22 so that communication betweenthe difierent tubes of the adjacent receptacles can be cut-off ifdesired.

In order that the user of the apparatus may be notified automaticallywhen the sup ply of water in the boiler should be replenished I providethe boiler with a gage 23, preferably in form of a glass tube whoselower end is fitted to the elbow 2A which extends from the side of theboiler, while the upper end of the tube has a cap 25 removably fittedthereto whereby the tube can be cleaned when desired. A lateralprojection 26 extends from the tube adjacent to the upper end thereofand fitted to the projection is a cap 27 whose outer end is open. Thiscap confines a whistle or like alarm device '28 to t-heprojection 26 sothat when the '30 which is disposed in the space 13 between the bottoms10 and 11. The walls of the projection '30 are-flared in the directionof the intake end of the valve so as to provide an annular seat 31 whosewalls may be frictionally engaged with a correspondingly reduced end 32of the tube 33. -This tube extends from a combined strainer andcontainer 34:. The strainer may be constructed of wire gauze or suitableforaminous material'and, as illustrated, at one end it has removablyfitted thereto a slide or closure 35. It is stated that the foraminousbottom 11 of the receptacle 4 is removable, whereby when desired thecombined strainer and receptacle 3% may be connected with ordisconnected from the valve 29 as to the requirement. The receptaclecarries a suitable gage glass 36 whereby the soup fluid during theperiod of consummation of the different commingled liquids may be viewedfrom the exterior of the apparatus whereby the fluid may be drawn off atthe proper time by the user. A suitable cover 37 is removably fitted tothe upper receptacle 7 of the apparatus.

oughly cooked. The vapors rising from the different products in thereceptacles pass to the drip tubes 19 where the liquid of condensationwill be discharged into the lowermost receptacle 4. In this waythedifferent vapors from the difierent food stuffs will be commingled toproduce a soup that may be drawn off through the valve 29. Spices or anysuitable flavoring may be placed in the receptacle 3 1 where it will besatisfactorily exposed to the commingled liquids whereby a desirableseasoned element will be made.

The receptacle 34, through the fact that it is disposed in the space 13and associated with the valve 29 serves to strain the liquid as it isdrawn ofi.

In the preferred embodiment of the in vention shown in Fig. l the steampipe sections 15 are supported upon one side of the structure while thedrain tubes 19 are supported on the opposite side of the structure.

In the modified form of the apparatus shown in Fig. 2 the steam pipesections 15 and the drip tube sections 19 are both supported on the sameside of the structure.
